An Efficient Constant-Coefficient MSAV Scheme for Computing Vesicle Growth and Shrinkage
Zhiwei Zhang, Shuwang Li, John Lowengrub +1
We present a fast, unconditionally energy-stable numerical scheme for simulating vesicle deformation under osmotic pressure using a phase-field approach. The model couples an Allen…

Membrane Heterogeneity Driven Dynamics of Multicomponent Vesicles in Shear Flow
Shuqi Tang, Steven M. Wise, John Lowengrub +1
Despite their significance in biology and materials science, the dynamics of multicomponent vesicles under shear flow remain poorly understood because of their nonlinear and strong…
